    • PURPOSE: An exhaust valve apparatus of a CNG(Compressed Natural Gas) engine with changing the contact angle between the valve and the valve seat is provided to minimize wear of the exhaust valve and the valve seat by inclining the contact angle between the exhaust valve and the valve seat of the exhaust port to the exhaust valve. CONSTITUTION: An exhaust valve apparatus of a CNG engine is installed in an exhaust port(12) of a cylinder head(10) to open and close the exhaust port. The exhaust valve apparatus comprises an exhaust valve(14) opening and closing the exhaust port, a coil spring(16) elastically pressing the exhaust valve, and a rocker arm(18) pressing the exhaust valve downward. The contact angle between an edge(20) of the exhaust valve and a valve seat(22) is inclined for the exhaust valve with 30 angular degrees. Wear between the exhaust valve and the valve seat is minimized with contacting the edge of the exhaust valve to the valve seat with little force.
